A superhydrophobic carbon nanofiber network inlay-gated mesh with high durability and separation performance was developed for oil–water emulsion separation.
Abstract Ocular drug delivery is an interesting field in current research. Silica nanoparticles (SiNPs) are promising carriers for ophthalmic delivery. However, little known about the toxicity of SiNPs on ocular surface cells such as human corneal epithelial (HCECs). In this study, we evaluated cytotoxicity induced by 50, 100 and 150 nm sizes cultured HCECs up to 48 hours. were up-taken inside cytoplasmic vacuoles. Cellular reactive oxygen species generation was mildly elevated, dose...
One important aspect of nanotechnology includes thin films capable being applied to a wide variety surfaces. Indispensable functions include controlled surface energy, stability, and biocompatibility in physiological systems. In this study, we explored the ancient Asian coating material "lacquer" enhance mechanical stability nanofilms. Lacquer is extracted from lacquer tree its main component called urushiol, which small molecule that can produce an extremely strong coating. Taking full...
Background: The purpose of this study was to analyze the upper eyelid contour normal adults and differences these according sex age in Asians using a software program that measures multiple radial midpupil lid distance. Methods: Conventional 12 oblique distances every 15 degrees across temporal (105, 120, 135, 150, 165, 180 degrees) nasal (75, 60, 45, 30, 15, 0 fields fissure 360 healthy Korean subjects older than 20 years younger 80 both sexes (30 each group) were measured custom software....
Although the wound healing effects of nitric oxide (NO) are known, mechanism by which NO modulates corneal remains unclear. In this study, we investigated effect exogenous donor (NaNO2) on healing. We found that NaNO2 (0.1 μM to 100 μM) increased human epithelial cell (HCEC) viability and migration. It also modulated phosphorylation mitogen-activated protein kinases (MAPKs) in a time- dependent manner those HCECs. Further, p38 MAPK at 6 h normalized 24 h, while extracellular signal regulated...
The objective of this study was to report the cause increased contrast sensitivity and improved functional visual acuity after upper eyelid blepharoplasty.Twenty-two eyelids 16 patients with dermatochalasis involutional ptosis were prospectively studied. Contrast sensitivity, corneal topography, high-order aberration (HOA), degree lash examined recorded before at 1 month blepharoplasty. A Wilcoxon signed rank test performed compare difference.The significantly in every spatial frequency...
The aims of this study were to evaluate the normal range dimensions lacrimal glands in healthy orbits Korean subjects and their association with clinical findings.A retrospective survey patients who had visited Korea University Medical Center undergone orbital computed tomographic scan was performed. One hundred eighty (90 men 90 women) older than 20 years without disease included. Patients trauma or any known gland excluded. length width measured axial coronal sections using largest image....
The objective of this study was to evaluate the association facial asymmetry and nasal septal deviation in acquired unilateral nasolacrimal duct (NLD) obstruction.A retrospective survey conducted 39 patients (6 male 33 female) who had undergone endoscopic dacryocystorhinostomy at Korea University Ansan Hospital. Patients with trauma orbit or any known lacrimal disease were excluded. primary goal obtain a descriptive analysis deviation. We analyzed results identified associations NLD...
To evaluate the type and cause of orbital blowout fractures in Korea.Retrospective, observational case series.Patients who underwent reconstruction for fracture from March 2004 to April 2013 at Korea University Guro Ansan Hospitals were included this study. Patient demographics computed tomography (CT) scans reviewed. On CT, ethmoid air cell septa, type, other combined analyzed. Blowout was classified as affecting up 4 areas: floor lateral infraorbital canal, medial maxilla-ethmoidal strut...
To investigate the alleviation effect of Vaccinium uliginosum extract (DA9301) on tablet computer-induced asthenopia. This was a randomized, placebo-controlled, double-blind and parallel study (Trial registration number: 2013–95). A total 60 volunteers were randomized into DA9301 (n = 30) control groups. The group received oral pill (1000 mg/day) for 4 weeks placebo. Asthenopia evaluated by administering questionnaire containing 10 questions (responses scored scales 0–6; score: 60) regarding...
Two patients with depigmentation and fat atrophy after an intralesional injection of triamcinolone acetonide (TA) to treat chalazion are reported. A 2-year-old girl in her right lower eyelid received a subconjunctival TA developed around the injected area. These changes subsided 7 months. The second patient was 5-year-old boy who into through skin also but these improved 1 year.
This study was undertaken to evaluate the clinical characteristics and efficacy of lateral tarsal strip (TS) medial spindle procedure (MS). We conducted a retrospective chart review patients who underwent TS MS between September 2008 July 2011 by single surgeon (S.H.B.). Data were collected on patient age, sex, laterality, diagnosis, procedures performed simultaneously, follow-up duration, postoperative complications, surgical outcomes. One hundred eleven eyelids 74 41 29 included in this...
Objective The objectives of this study were to report the success rates for perforated punctual plug (PPP) in management acquired stenosis and evaluate factors influencing rates. Design This was a retrospective, cross-sectional, comparative study. Participants There 20 patients. Methods Twenty eyes patients who underwent PPP implantation obstruction retrospectively evaluated regarding sex age duration severity epiphora, associated blepharitis, treatment. In all patients, punctum dilation...
Purpose: To report adverse hemorrhagic outcomes in patients who received intravenous (IV) ketorolac during oculofacial plastic surgical procedures. Methods: The medical records of 111 consecutive underwent lacrimal or orbital surgery, between the years 2016 and 2018, performed by a single surgeon under general anesthesia were retrospectively reviewed. Patients excluded if they had history bleeding coagulopathy, anticoagulant use prior to insufficient follow up. divided into 2 groups based on...
To present a transconjunctival and transcaruncular endoscopy approach involving layered porous polyethylene barrier implants to manage residual posttraumatic enophthalmos evaluate the effectiveness of this technique.The authors performed retrospective review all patients who underwent secondary reconstruction orbital wall fractures because between June 2008 July 2015. Patients' demographics, degree enophthalmos, ocular motility, diplopia test results, surgical complications were...
